Water well drilling tools are the main tools we use for drilling and mining, so what are the advantages of using water well drilling tools? The following water well drilling tools manufacturers bring you the advantages of using water well drilling tools

　　1. Concepts such as the oblique cutting index and anisotropy index of the drilling rig bit, and the comprehensive cutting preparation anisotropy index, etc., derive the general Nongda formula and the natural deflection force of the formation suitable for the actual drilling rig bit, volume crushing and surface crushing conditions. Simplified form; using the drilling rig WOB cone method to deduce the calculation formula of the formation congruent force and the formation azimuth force in directional drilling, which provides the basis for the analysis of the formation force for the directional and orbit control of the drilling rig. It has been verified that the theoretical analysis results are in good agreement with the drilling practice.

　　2. The formation is oriented and small, the deflection force and the formation variable force, the inclination angle of the spoon, the weight on bit, the formation dip, the anisotropic cutting anisotropy index of the drilling rig bit, the formation anisotropy index, the wellbore orientation and the formation Tilt azimuth force, and possibly reduced azimuth force. Under normal circumstances, the stratum variable well inclination force makes the drill bit trajectory of the drilling rig move closer to the normal direction of the stratum, and the stratum variable azimuth force makes the wellbore azimuth move closer to the stratum inclination azimuth. When the orientation of the wellbore of the drilling rig is consistent with the orientation orientation of the formation, the orientation changing force of the formation is zero.

　　3. On the basis of the proposed new concept, the critical formation dip equation is found, which provides a preliminary quantitative explanation for judging the trend of the drill bit.

　　4. The formation force of the drilling rig is proportional to the WOB, increasing the WOB will significantly increase the formation force.
